Hello everyone, my name is Mike and I ride bikes. A little background of myself. I currently ride mtb's. Own a 160mm trail bike and a 140mm hardtail. I'm 57 and am in pretty good shape.Over the last few years I've been riding a lot of rail trail, we have miles and miles of top notch trails, north east Pennsylvania. I've been using my hardtail, it is a bit to much bike for what I'm doing. Nonetheless I'm putting a ton of miles on it. Been doing some research on building a gravel bike to use for that purpose. I'm looking to pull the trigger on a Ridley X-trail carbon frame. I'd like to build up as a 1x11 drivetrain. The BB has me a little confused, PF86. I found a chart from problem solvers which says it was designed for 24mm spindle, hollowtech or gxp. My ? is will any gxp crankset work with this bb? Please forgive my ignorance on road standards, I have no experience with it. Sram (gxp) has a lot of 1x options. Any help would be greatly appreciated. I will do a 2x if I have to. Again thanks, Mike
Hey Noodle, thanks for the reply. I've done some more poking around the internet and found some good info. I did order a frame and a bottom bracket. I got the wheels mfg BB86 for gxp cranksets that you mentioned. I have an older Sram carbon crank that should work. You are on the other side of the state from me. I'm located in Lackawanna County.
I too went with a Wheels Mfg on mine when I upgraded, they make nice stuff (I stayed 2x). The bearings on mine are plain jane and outdated by now looking at their current offerings, but easy/cheap to replace (I haven't had to yet). Good choice.

After couple years I upgraded (downgraded?) to Praxis subcompact with the WMFG thread together bottom bracket. (Not sure what size)
The point is it will work with whatever road crankset you'll get, as long as you use the correct BB: -> PF86 to whatever your crankset is.
Btw, I'm in Erie PA, which might not be too far from you!
I'm from Buffalo, and I was thinking he was talking about North East, PA as well! Haha...
Mikeonabike everybody has their thoughts on 1x or 2x. I have both. A 2x on a Raleigh Tamland 1 and a 1x Sram Rival on a Raleigh Roker Comp. I love the Roker but hate the 1x. It is alright if you are riding by yourself but terrible if you are riding in a group as there is too much of a jump in the gears in the lower gears.
Thanks for the replies fellas. I didn't know there was a town called North East. My current bikes are both 1X. I plan on using a wide range cassette. I'll have to figure out the front chainring size. I'm mostly a solo rider, occasionally ride with a buddy.
During the build up I noticed that my rear wheel when mounted favors the non drive side seat and chain stays. The wheel is a Stans grail with a hope pro4 hub. My local bike shop built them for me. They have built at least 3 previous wheelsets in the past and have never experienced this. Is this normal for this bike? The rear axle doesn't bind leaving me to believe everything is squared. The wheel spins true. Standing behind the bike the wheel seems to be inline with the front triangle.I reached out to Competitive Cycle and am waiting for a reply. On another note I went with a Praxis Zyante single ring crank set with their BB86 adapters. They do make a nice product. The direct mount uses a Sram interface so replacing rings would not be a problem. For you fellas that own a carbon Ridley X trail could you put an eye on yours and see if yours is centered in the stays and let me know. Thanks in advance. Mike

Unfortunately you can't eyeball these things. The frame might seem straight to your eyes but something could easily be out of whack. But i'm guessing it's most likely the wheel.
I think your options are:
Put a different wheel in the frame, check the new wheel or have the bike shop check it with a dishing gauge (of course they should have used one when building the wheel, but sh*t happens, people make mistakes), and you can do a string test on the frame to check if it's straight.
HollyBoni thanks for the tip. I pulled the wheel from my hardtail, removed the tire and mounted. It was dead center in the stays. The thought didn't occur to me to try another wheel. I called the shop and they're gonna fix it for me. The wheel I used to check was built by the same fella. Again thanks.

Finished my build. Really happy with this bike, very comfortable. Ridley X-Trail carbon, size small. Rolling on panaracer gk sk's, 700x38, on Stan's grail rims tubeless. Shimano ultegra shifters/brakes, and a ultegra rd with clutch. Brakes are hydraulics with galfer rotors, 160f/140r. Drive train is a Praxis 40t Zyante aluminum crank with a shimano xt m8000 11/40 cassette. Easton 70 series carbon bars and seat post, and a Selle Anatomica saddle.Bought a Oveja Negra 1/2 frame bag to put on it. The bag is awesome. I haven't taped the bar yet, still tweaking the position of the shifters.
My current bikes are both 1X. I plan on using a wide range cassette. I'll have to figure out the front chainring size. I'm mostly a solo rider, occasionally ride with a buddy.
